s2000 gauge cluster in a 2nd gen teg?

SO an opportunity has presented itself. I am able to get an s2000 gauge cluster and all wiring. engine start, theft deterent wiring etc. My question is how hard is this wiring going to be. I think the gauge cluster has to get a signal from the ????ecu???? for the theft deterrent program? Something like that I'm not sure, but it be sweet in my car. Even if i have just set it on top of my dash!

i think rywire sales the kit, best thing to do is call them and tell them what year gauge cluster it is and what car its going in, you have to have few new things and wires for all the stuff to work right, they will sell you a kit to make it plug and play
